Salmonellosis causes significant health and economic problems in poultry industry, but it may also occur in extensive poultry production with higher or lower prevalence. Since salmonellosis is a zoonosis, it plays an important place among other major pathogens in poultry. The most important Salmonellae, present both in animals and humans, are Salmonella enteritidis i Salmonella typhimurium. The aim of this research was to determine if there is a correlation between positive bacteriology and serology examinations carried out by ELISA test immediately after the slaughter. From the obtained results it may be concluded that there is a correlation between positive bacteriologcial findings and serological examination. Serological monitoring successfully detected infected flocks even when bacteriological findings were negative. A possibility of transmission from the parental flock to broiler chickens, as well as spreading the infection within the broiler flock, is considerably higher in non-vaccinated comparing to the vaccinated flocks.
